Prestress empty box type retaining wall
The invention discloses a prestress empty box type retaining wall structure which comprises a box type retaining wall, a wall top cover plate and a prestress anchoring system. The box type retaining wall is of a hollow structure, is formed through a reinforced concrete cast-in-place process and is composed of a hollow face plate, a bottom plate, a face plate cavity, a reinforcing rib plate, a drainage pipe and a drainage groove. The wall top cover plate is composed of a cover plate face plate and a cover plate boss, is arranged on the top of the box-type retaining wall and is embedded into a face plate cavity. The pre-stressed anchoring system comprises pre-stressed steel bars, anchoring grooves, anchor head clamps, corrugated pipes and anchoring plates, and pre-stress is applied by adopting a post-tensioning process. The retaining wall is simple in structure, large in bearing capacity and capable of meeting the bearing requirement for the wall height of 10 m or above; construction is convenient and efficient, the overall performance is good, the cost performance is outstanding, a counterfort retaining wall can be effectively replaced, the influence on backfill rolling construction is reduced, and the engineering application prospect is huge.
本发明公开了一种预应力空箱型挡土墙结构，包括箱型挡墙、墙顶盖板和预应力锚固系统；所述箱型挡墙为中空结构，采用钢筋混凝土现浇工艺成形，由中空面板、底板、面板空腔、加强肋板、排水管、排水槽组成；墙顶盖板由盖板面板和盖板凸台两部分组成，布设于箱型挡土墙墙顶，并同面板空腔相互嵌合；预应力锚固系统包括预应力钢筋、锚固槽、锚头夹具、波纹管和锚定板，采用后张法工艺施加预应力。该挡土墙结构简单、承载能力大，满足10m以上墙高的承载需求；其施工方便高效、整体性能较好、性价比突出，能够有效替代扶壁式挡土墙，减少对墙后填土碾压施工的影响，工程应用前景巨大。
